If you are looking for a bike with better mileage and a more premium look, the Yamaha MT 15 V2 might be the better choice, offering around 56.87 kmpl and a more refined handling experience. However, if you prioritize performance and a sportier ride, the Yamaha R15S, with its 18.6 PS @ 10000 rpm power output and dual-channel ABS, could be more suitable. The MT 15 V2 is priced slightly higher at around ?1,70,086 compared to the R15S at ?1,67,559, but it also offers better comfort and a more stable ride. Ultimately, the decision depends on whether you value mileage and comfort or raw performance and a sporty feel.
